It's another CLE weekend!
During these stressful times, the CLE might hopefully provide some peaceful relief for you.
'CLE's are 'Co-ordinated Listening Events, and NDB DXers around the world focus their listening time on one small slice of the NDB spectrum.
This time the hunting ground is the 15kHz slice from 385.0 - 399.9 kHz. kHz
A good target for this one is little 'OO' (391kHz) in Oshawa, Ontario, shown above. 'OO-391' has a measured output of just over 7 watts yet is heard consistently all over North America including the west coast as well as in Europe! Hearing 'OO' is a very good test for your receiving system!
Listen for 'OO's' upper sideband on 391.402kHz with your receiver in the CW mode.
From CLE coordinator Brian Keyte (G3SIA), comes the following CLE info:
Have you tried one of our Co-ordinated Listening Events yet?
Whether short logs or long ones, making them is enjoyed by
beginners and experts alike - and reading them is enjoyed by all.
Our 255th Coordinated Listening Event starts this Friday. We
should have plenty of NDBs to find in this 15 kHz frequency range.
Even the Pacific region (Oceania) is quite well supplied this time.
Days: Friday 24 April - Monday 27 April 2020
Times: Start and end at midday your LOCAL time
Range: 385 - 399.9 kHz
Please log all the NDBs that you can identify with nominal (listed)
frequencies in the range - it includes 385 kHz, but not 400 kHz
- plus any UNIDs that you come across there.
Send your final log to the List (no attachments please and ideally
in a plain text email) with 'FINAL CLE255' in its title (important).
Show on each line:
# The Date (e.g. '2020-04-24', etc., or just '24' )
# The Time in UTC (the day changes at 00:00 UTC).
# kHz - the nominal published frequency, if known.
# The Call Ident.
Please show those main items FIRST. Other optional details
such as Location and Distance go LATER in the same line.
As always, of course, tell us your own location and give brief
details of the equipment that you were using during the Event.
We will send the usual 'Any More Logs?' email at about
19:00 UTC on Tuesday so you can check that your log has
been found OK.
Do make sure that your log has arrived on the List by
08:00 UTC on Wednesday 29 April at the very latest.
We hope to complete making the combined results within
a day or two.
You can find full details about current and past CLEs from the
CLE page http://www.ndblist.info/cle.htm It includes access
to the CLE255 seeklists for your part of the World, prepared
from all the previous loggings in Rxx.
- enjoy the CLE and take care.

(If you would like to listen remotely you could use any one remote
receiver for your loggings, stating its location and owner and with
their permission if required. A remote listener may NOT also use
another receiver, local or remote, to make further loggings for the
These listening events serve several purposes. They:
- determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date
- determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range
- will indicate the state of propagation conditions at the various participant locations
- will give you an indication of how well your LF/MF receiving system is working
- give participants a fun yet challenging activity to keep their listening skills honed
The NDB List Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. There is a lot of good information available there and new members are always very welcome. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.
You need not be an NDB List member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers.
Remember - 'First-time' logs are always VERY welcome!
Reports may be sent to the NDB List Group or e-mailed to CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above. If you are a member of the group, all final results will also be e-mailed and posted there.
Please ... give the CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.
Have fun and good hunting!
